good day. im currently doing some wet plate work. I have a mini speed graphic and I've succesfully converted a graphic filmpack adapter to hold tintypes.

question is I've recently acquired a Meridian 45a press camera and was wondering If I can go the same route. are 4x5 graphic film pack adapters universal? standard? I just want to make sure it will slide in the Meridian before I start bidding on some. forgive the ignorance but any info is greatly appreciated.
